crayfish with natives

[mopani]

I will have a 150 long for a native in my new fish room, thank God, been talking natives for a year and a half, it will be sunfish and gills. To keep the lake theme, could I add some crayfish to hide in the rock formations I wanna do? Not caring if fish eat them but would they hurt the fish, I figure the fish will be to big and fast but wanted to run it by the pros here

Ive kept crays and natives with many different tanks. I like using large gravel and cobblestone for substrate since they bulldoze anything finer. crays are good hunters and they are always dangerous to small fish, but a proper size difference should keep that from happening. IME, sunnies are very capable at avoiding dangers. Given a proper number of escape routes and hides, sunnies should have no problem co-inhabiting a tank with crays
